That's an excellent question, Danielle!
Your course is integrated with your school's Canvas--so you can only click on the WileyPLUS links provided to you in the modules or assignments area. These are provided by the instructor.
If the course is deep-linked, then you'll find direct links to your individual assignments in Modules. If it is not, you'll find either a WileyPLUS Homepage link or a WileyPLUS Assignments link.
The assignments will take you to them, whereas the Homepage will allow you more of a free access--in which case, you click on the Assignment tab.
If you have neither--reach out to your instructor who can provide the links for you.
Thanks for reaching out!
Tom with Wiley
